Master of Disaster Roland Emmerich certainly loves ancient alien theory, and I believe Stargate (1994) helped cement his status in this subgenre. He’s been to space and back with Moon 44, but that wasn’t the movie which started it all. He’s better known for Independence Day and in that regard, Moonfall is familiar.
This movie is hilarious to watch because we know the tropes he loves using, and he regurgitates those ideas well. This filmmaker introduces Brian Harper (Patrick Wilson), an astronaut who gets canned because he failed in one mission. His peers don’t believe he saw a swarm of cosmic mist that caused his crewmates to die. He’s somewhat similar to Steven Hiller–Will Smith’s character.
On Earth, K.C. Houseman (John Bradley) is a conspiracy geek who uncovers the truth and is much like David (Jeff Goldblum’s character). This actor is good in the role, but I suspect casting wanted Jack Black. He’d be great at injecting some craziness to why nobody buys into what he discovered. The sky is falling! The moon is coming out of orbit and will soon cause world-wide devastation.
